CHARLES R. MABEE, 0F TOLEDO, OHIO, ASSIGNOR TO LONG POINT CREAMERIES COMPANY, OF TOLEDO, OHIO.

AIR HEATER AND DISTRIBUTER.

Application filed December 15, 1913, Serial No. 806,893. Renewed February 26, 1919.

To all whom it may concern:

Be it known that 1, CHARLES R. MABEE, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Air Heaters and Distributers, of which the followingis a specification.

This invention relates to air heaters and distributors and especially to that class of heaters which are employed. for heating residences and other buildings. It provides means for the application of centrifugal force and circumferential motion to a thin cylinder or film of air forced around and against the concave cylindrical walls of a heater and means for forcing air. so heated to the various parts of a structure.

To enable others skilled in the art to which it pertains to make and use the same, I will proceed to describe the invention with reference to the accompanying drawings, in which similar reference characters refer to similar parts in all the figures.

Figure 1 is a vertical longitudinal section of my. improved device, with the attached pipes and driving means in elevation, Fig. 2 is a transverse section of the same along the line 2-2 of Fig. 1, Fig. 3 is a detail view of an alternative form of heater without corrugations, showing the attachment of the longitudinal blades.

Referring more particularly to the drawings, 1 designates the heater, which is essentially a horizontally disposed cylinder provided with an, external jacket 16.- mounted on a support 18 and provided with a P1111 rality of suitable heaters 9, here shown as vapor burners". The heater is supported in horizontal position by pedestals 15 and the cylindrical wall 11 thereof is provided with circumferential corrugations and a flue 12 connected to the jacket and provided with a damper 2O furnishes escape for the gases" of combustion, suitable air inlets to the burners being shown at 17. Extending centrally and longitudinally of the cylinder is a shaft 2 supported for rotation in bearings 22 and 23 at the ends of the cylinder. Located within the cylinder on the shaft at opposite ends thereof are supporting rings 14, said rings being arranged concentrically with the walls of the cylinder and connected Specification of Letters Patent.

with the shaft by radially extending arms 14' that connect. with central hubs 145- fixed to the shaft. Extending longitudinally of the cylinder are a plurality of blades 10, said blades being connected at their opposite ends with the respective supporting rings 11 and being arranged in a circle adjacent the periphery or walls of the cylinder, said blades being closely associated and equally distanced from each other. The blades 10 preferably take the form illustrated in the drawing, in-which they are shown as bars that are substantially L-shaped in cross section. the bars having one of their flanges secured to the rings, the other portion or flange extending outwardly toward the wall of the cylinder. As illustrated in the drawing the blades 10 extend at an angle to the longitudinal axial line of the cylinder. Arranged within the space at the interior of the supporting rings 1-1 and the longitudinally disposed blades 10, are radially extending blades 3, said blades being arranged in sets intermediate the ends of the longitu- 4, connects with a distributing pipe 26 provided with a damper 19. The distributing pipe 26 has a plurality of branches 26, shown cut away, and adapted to lead to various rooms or the like for heating purposes. A flexible tube 8 is here shown as conveying fuel to the burners 9.

The operation of my device is as follows:

The burners 9 having been lighted, the valve 6 in the pipe 7 is opened and the motor 5 is started'connnunicating rotary motion to the shaft 2, the fan blades 3, the rings 14 and the blades 10.. Un der' the influence of the fan blades, air flows into the container .1 through the inlets 4 and has communicated to it, rotary motion in the direction of the revolution-of the shaft and fan blades. Under the impulse from the blades 10 of L cross-section; air is forced against the corrugated surface of the wall 11 of the container and a thin cylinder of air is heated to aihigh temperature. The air thus heated is forced into the outlet 13 and is distributed through pipes 26 to parts of the building where heat is desired. The wall 11 may be constructed without corrugations.

While the construction set out is excellently adapted for the employment of my invention in practice, I do not limit myself to the details as they may be modified Without departing from the spirit of my invention.
